This is a great desktop gadget! It is fairly simple to instal and use, (i’m using vista) it also works well with programs like photoshop, under “import”

the settings make it quite versatile and you can choose a range of capture sizes.

The wheel allows focussing in either 20X or 400X (nothing in between) and at 400X the depth of field is quite shallow, so the object needs to be very close to the end of the microscope, and you have to be very gentle to get it in focus!

The microscope has a handy cap on the end which allows you to hold small objects or insects at just the right distance.

The supplied software is not bad either. it gives you access to all the settings and even allows you to measure the object usingthe scale on the focussing ring.

As with most reviews the stand is a little on the light side but is more than suffiecient to hold the microscope.

Well Recommended!

Thanks to amazon it arrived the day after it was delivered!!

I have just taken delivery of the VMS-004 microscope. It works (eventually). As with many other reviews (including those on the VMS-001) I have to say that the instructions are less than helpful, both on the installation and the use of the scope. I suspect my problems have been similar to those mentioned in the other reviews, so apologies if I repeat some comments. And some of my problems have been the usual ones arising from not fully reading the documentation that did exist (although I had to read between the lines on quite a few points).

My first attempt at installation … having read the reviews I skipped the instruction in the skimpy Quick Start Guide to plug in the scope before installing, so (using the supplied disk) the driver installation stopped and said it couldn’t find the device, please plug it in! So I plugged it in and all went OK.

Starting the Microcapture software and up came a preview screen that looks terrible at first, but twiddling the knurled silver wheel brought things into focus. BUT the magnification looked nothing like the 400x promised – more like 12x. Turning the wheel did not zoom (as implied by the scale shown on the device), it is a Focus wheel (as it calls it in the manual) and the meaning of the scale was not immediately apparent. The use of the wheel is simply to focus on objects at different distances from the nose of the scope.

Changing the preview size (initially set at 640×480) to anything above 640×480 hung the software – which with hindsight could be a memory problem on my machine.

Thinking I may have had a software problem, I removed the Digital Microscope driver and Microcapture (via the Control Panel in XP) and downloaded the ‘latest’ software from the Veho site, unpacked the Zip, ran Microcapture.exe (i.e. the menu shown in AutoRun.inf) and reinstalled the driver and software. The NEW manual does say NOT to plug in the device before the installation. I did the installation OK then plugged in the scope, and XP seemed to find the device and driver OK. BUT Microcapture now said it couldn’t find the scope, though XP could see the device. I tried a few things, but gave up, uninstalled and reinstalled using the CD (thinking it was better to have low magnification than no magnification!).

THEN I FOUND SOMETHING. Keep turning the knurled knob to the extreme ‘other’ end of its movement (ignoring the ‘direction’ of the scale) and there is a second focus point (as I then recalled reading in a review somewhere)! I reckon the magnification of a subject placed at the end of the plastic tube (having removed the clear cap) looked like about x250 on the preview window – not the advertised x400, but pretty good. When you think about it, it is obvious that the ‘magnification’ depends on how much you blow up the image.

THEN I READ THE MANUAL BETTER. When you do focus on an object near the end of the clear tube, the scale gives you a ‘notional’ magnification. If you then capture an image and open it in the Microcapture software (double click on the thumbnail), you enter that number on the preview screen and using the measurement ruler will give you a fairly accurate measure of the object seem in the image. The actual ‘magnification depends on things like the resolution of your screen. I reckon the x400 would really be x400 if the image was printed at about A4 or a bit bigger.

The two focus points effectively give you something like x400 at one end and x20 at the other – i.e. the advertised x20-x400 doen’t mean x20 TO x400 but x20 AND/OR x400.

So the ‘old’ installation using the supplied CD seems to works – the software still seems to hang with higher preview sizes, but hey, I have a working microscope. The ‘updated’ software doesn’t seem to work at all (on my machine). And as a PS on the new downloaded software, the ‘Install me(tm) software’ option is never explained in the (new) manual – it seems that its a peer-to-peer client for the Diino online storage facility – something I wouldn’t touch without knowing more about it and I can’t think that it is in any way necessary for using the scope.

There’s a moral in all this somewhere, but I’m not a philosopher!!

And as a Postscript – the driver for the scope is a Twain driver and works in File>Import in Abobe Photoshop (VMUVC Twain Driver) – and in that context the higher resolutions work OK if a bit slowly.

This gadget is great! Who cares what the actual magnifications are…I have latest Windows 7, 64 bit & had no problems installing the device…images are crystal clear…infact, images are clearer than my equipment at work which cost over 4K! Say no more…buy it!

People saying that cant get it to work… get in focas of the 20x image… now move the focas nob all the way to 400… Now keep going past that… and begin looking for your 400X Focas point…. you will see it if not change the distance closer closer closer to the image until you see it.. People saying its only 20x because they dont know how to use the scope are stupid lol

I recently bought this digital microscope and received it today.
I’ve read the quick start guide, plugged in the device and installed the drivers (using Win 7 x86). I usually install all my programs on another partition D instead of C. After rebooting I opened the program but the microscope was “not found” :s
I was already dissapointed. Then I remembered I had a program in the past wich wouldn’t work if it was installed on another partition than C. So I removed the drivers and program from the microscope and reinstalled them but this time in C:/Program Files and indeed… it worked! I still have to experiment a bit with it but at first I could only zoom up to 20x (I thought!) so again I was dissapointed. However, after doing a little experimenting I found that the microscope has to be VERY close to the object and if you then go to 400x and very slowly move the adjustable wheel you can zoom much much deeper at a reasonable quality. It’s still not superb (doubt it will be) but as I said… need to do more experimenting.
All in all not a bad gadget as I’ve bought it of eBay for half the price

There’s room for improvement on the software though. The biggest thing I miss is zooming through software instead of the wheel. This would make it much easier to get a clear image because now you have to use the wheel but at the same time you’re moving the microscope. At 400x that’s not a good thing…

I’d give it a 4/5 (nice gadget for it’s price but there’s still room for improvement)
